Fun fact! The development of ailerons led to the "Wright Brothers Patent War." Ailerons (such as the ones attached to the far end of the wing of this Curtiss Model D) emulate lateral control such as that produced by the Wright Brothers' patented method of wing-warping.
During the patent war that ensued the Wright Brothers sued foreign and domestic aviators and companies, especially U.S. aviator Glenn Curtiss. Some historians claim the "patent war" may have stalled development of the U.S. aviation industry. #oldrhinebeckaerodrome #thewrightbrothers #glenncurtiss #ailerons #patentwar #redhooklibrary
